Aluminum

[whiskey]

Pic1) 2mm aluminum sheet started good doing the melting pool.

Pic2) The next day l carrion practicing then this happened.

Pic3) l checked with the hand trigger.

I yous'd the blue stunystan could be contamination or l have a problem on my R-tech 161amps.

Is your gas flow ok? the soot looks like poor gas flow/coverage

 

[BrokenBiker]

looks like there is no gas there, or there is a contamination of the gas like an air leak dragging in atmospheric air to the argon system

 

[Piero]

Guess he forgot to turn the gas on

 

[Tinbasherdan]

Most definitely a gas issue there

 

[Appyasme1]

First of all,are you using pure Argon?

Is your machine new? If so its almost certainly a problem with the set, as none of the R-Tech sets are checked before despatch, and seems like DOA or failure within a few days is pretty common.

deffo looks like you have run out of gas, or have a gas issue of some description.

Just checked the gas flow is ok.

 

[Tinbasherdan]

What do you call ok? What lpm? And are you using pure argon?

Looks like what you are saying is the problem Chris.Yes the machine l bought it new l have it for a some time now. And now l got a regulator with a flow meter. Thing is that the melting on the first day was perfect it was doing it properly and the next day it was not melting it was even burning the tungsten. Have to give R-tech call then.?

Yep argon

What's DOA?

Must be the setting's

No it was ok

Yep argon

 

[mr migwire]

do you have gas at the torch when you press the button?

 

[Tinbasherdan]

Show us your torch set up, there's something drastically wrong somewhere . They are classic signs of gas shortage, you want around 7-9lpm of gas really , have you made sure the fittings are tight in the torch body

what evidence do you have for this? from what i can see the machine is welding but there is little to no gas flow, which to me and most others here says that either the bottle has run empty, there is a blckage somewhere in the system or there is an air leak that is dragging atmospheric air into the argon and diluting it

i was trawling through google looking for reports of dead machines and can't find any.... my 161 is great as is my r-tech plasma cutter and stick inverter. definitely a lack of gas, perhaps a sticky solenoid or as BB says a leak somewhere or air being drawn in....
